Problem with custom code on video intro

Site URL: https://www.iambabydogg.com/

Hi, 

Wondering if anyone in the community is available and /or able to help us with a custom code issue? 

We have a website that had a custom code video intro... and for some reason it's not loading properly. 

On the backend - editing /admin side - it looks normal like everything is right. 

However, there is some problem with it loading on the front end when you go the website iambabydogg.com

See screenshots on attachment. The black screen is what it looks like to us when we go to the site.. 

the version with image is from the editors panel and is what it should look like with the video pre roll intro. 

This is all support would give me https://support.squarespace.com/hc/en-us/articles/205815928

Thank you 

@evolvinggraphicswhy don't you remove the custom code and use a background video or cover page
